1. what are the estimates for projects like this (with working product) if crypto market explodes again?
There is no estimate because the sky is the limit if the market explodes again. Of course, if the project survives until the next bull market(if any).
2. Do i even stand a chance getting any reward in trading competitions?
Only you know it, do you have a deep pocket or not to help you do the trade? if you think you can do it, then give it a try.
